Callio is a unified API gateway for AI agents. Instead of managing auth, rate limits, and keys for every API your agent uses, connect them all through one proxy. Works with Claude Code, Cursor, Antigravity, and any MCP-compatible tool. Browse APIs, generate a single Callio key, and start calling — we handle auth injection, usage tracking, and billing. Free tier included. One key, every API, zero config

Hey Product Hunt! 👋
I built 𝐂𝐚𝐥𝐥𝐢𝐨 because connecting AI agents to external APIs is a mess. Every API needs its own key, auth setup, and error handling. It doesn't scale.
𝐂𝐚𝐥𝐥𝐢𝐨 fixes this with one unified API key that works across every API in our marketplace.
➜ Browse APIs on callio.dev
➜ Click "Add to Agent" to get your key
➜ Your agent calls our proxy, we handle auth and rate limiting
𝐖𝐡𝐲 𝐂𝐚𝐥𝐥𝐢𝐨:
✅ 𝐌𝐂𝐏 𝐒𝐞𝐫𝐯𝐞𝐫 support for Claude, Cursor and Antigravity
✅ 𝐑𝐄𝐒𝐓 𝐩𝐫𝐨𝐱𝐲 for any AI framework
✅ Real-time 𝐮𝐬𝐚𝐠𝐞 𝐝𝐚𝐬𝐡𝐛𝐨𝐚𝐫𝐝
✅ 𝐅𝐫𝐞𝐞 𝐭𝐢𝐞𝐫 with 50 requests/month
🔥 You can try the APIs live at callio.dev/browse, no signup needed to explore!
One key. Every API. Zero config. Try it at 𝐜𝐚𝐥𝐥𝐢𝐨.𝐝𝐞𝐯 🚀

This is one of those why didn’t this exist earlier products Managing API Keys across agents is such a headache if Callio truly makes it one key for everything thats a big unlock.

I love how you are focusing on the boring but painful parts auth injection rate limits billing thats exactly the stuff that shows down AI experients Feels very developers first.

I can see this being especially useful for hackathons and rapid prototyping less time configuring, more time actually building the agent logic. Solid timing for this launch.
